tainer which can be held open by a slightv pressure of a thumb or finger and which will automatically close when such pressure is released.

I attain these'objects-by the means illustrated in the accompanying drawings in which,

Figure 1 is a plan view of the fixed cap; Fig. 2 is a plan vview of the fixed cap with the spring secured in position therein, but omitting the perforations; Fig. 3 is a plan view of the movable cap; Fig. 4 is an elevation of a can with the movable cap in place thereon. Figures 5, 6 and 7 are edge views respectively of Figures 1, 2 and 3; Figures 8 and 11 are plan views respectively of varied forms of caps permitting the use of a bent spring in place of the straight spring shown in Figure 2; Figure 9 is a plan view of such a cap with the bent spring in place therein; Figure 10 is a plan view of the movable cap as mounted upon the fixed cap shown in Figure 9; Fig. 12 is an edge view of the side walls of a variant form of cap'adapte'd to enclose the ends of the bent spring; Fig. 13 is a plan view of the fixed cap with a hairpin shaped spring inserted in place therein and showing the side walls of the movable cap mounted upon the fixed cap but with the top of the movable cap removed; Fig. 14 is a detail view of the spring in hairpin shape so that either end of the spring may act .upon the movable cap; Figures 15, 16, 17 and 18 are detail views of variant forms of spring which may be used.

My invention comprises a can, N, which may be of tin or any other suitable material having a perforated fixed cap, A, secured thereto and a movable cap, B, mounted upon the fixed cap and secured in place by an in turned flange, J.

The fixed cap, A, is provided with a depression which may be Y-shaped as at K, to utilize a straight spring, F, or which may be U-shaped as at L, to utilize a bent spring or hairpin-shaped spring, G. When the straight spring, F, is used, the side of the movable cap is provided with a perforation through which the end, P, of the straightspring, F, may project. WVhena curved spring is used assho'wn in Figure 9, a similar perforation is provided in the side of the cap through which one end, P of the spring may pro ect.

WVhenthe hairpin-shaped spring is used, the side walls of the movable cap may be formed with an extended portion, M, which extends beyond the ends of the hairpin spring and allows the shoulders, h and i, to engage the ends, S andP of the hairpin spring so that when the cover is revolved in one direction, the shoulder, 2', will act against the end, P of the spring, and when revolved in the opposite direction, the shoulder, it, will act against the end, S, of the spring. 'In either case, the spring acts against the movable cap to return it to its normal position when released.

The movable cap is provided with perforations which correspond to perforations in the fixed-cap and when in normal position, the movable cap closes the openings in the fixed cap and prevents the escape of the R powder, but is so formed that it can readily be revolved by a slight pressure of thumb or finger upon the end, P, of the spring or upon the extended portion, M, of the cap, so as to cause the perforations in the movable cap to register with the perforations in the fixed cap and allow the powder to be sprinkled from the can.

WVhen a straight spring is used, it is secured against longitudinal movement in one direction by the fact that the inner end of the spring will come in contact with the inner face of the side wall of the movable cap and it is secured against longitudinal movement in the opposite direction by the shoulders, e and d, which are formed integral with the spring and bear against'the inner face of the wall of the movable cap adjacent the perforations through which the end,

P, of the spring projects. The U-shaped spring will be held against longitudinal movement in one direction by the, sides of the depression, L, and against longitudinal movement outwardly by contact with the inner face of the wall or flange of the movable cap.

It is obvious that various other forms of depression in the fixed cap and spring may be used which will allow the flat, inner surface of the face of the movable cap to lie in close contact With the outer surface of the face of the fixed cap or the spring may have one end secured to the can or fixed cap by soldering or Various other methods and the ther end adapted to engage the movablecap and return it to normal position when released. I therefore do not limit my invention to the precise form of depressionand spring shown.

Neither do 1 limit my cap to the form shown in Figure l, for it is obvious that a slight bead may be rolled in the walls of the fixed cap and the movable cap which will have the same retaining efi'ect as the flange, J.

My invention is particularly useful for talcum powder or toilet powders of various kinds Where the cans are likely to be tipped over or Where they are carried ina satchel, handbag or other carrier.

I claim:

1. A powder container comprising a body having a perforated cap secured thereto, a

depression formed in the outer face of the fixed cap, a hairpin-shaped spring seated in the depression with ends projecting slightly outwardly therefrom, a movable cap revolvably mounted upon the fixed cap and having corresponding perforations, and also having a segment of its side wall extended outwardly and forming shoulders adjacent the projectingends of the spring.

2. A powder containercomprising a body having a perforated fixed cap secured thereto, a depression formed in the face of the fixed cap, a hairpin-shaped spring seated in the depression with ends projecting slightly outwardly therefrom, a cap seated upon the fixed cap having corresponding perforations and reciprocably revolvable thereon for a limited distance, said movable cap also having a segment of its sidewall extended outwardly enclosing the projecting ends of the spring and forming shoulders adjacent thereto.

In testimony whereof he afii xes his signa tu-re.
